OSHA classifies office workers as being at risk for repetitive strain injuries if they sit more than 4 hours a day. The average dental hygienist is seated 6-10 hours a day, in a static asymmetric posture, performing fine motor tasks at the sub-millimeter level, while also somehow maintaining a pleasant conversation about someone's vacation to Cabo. But sure. The office worker gets the $1,200 ergonomic chair with lumbar support, adjustable armrests, and a headrest. You get a vinyl circle on a gas cylinder from 2009. Research shows dental hygienists report musculoskeletal disorders at rates exceeding 70%, with the neck and low back being the primary complaint areas. That's not a coincidence. That's what happens when the most physically demanding seated profession in healthcare gets the least investment in seating. Crown Seating exists because someone finally did the math and said "this is absurd."
